Abstract

Spectral scanning magnetic resonance imaging methods and systems. In preferred methods and systems of the invention, to measure the resonance spectrum of the target object, a plurality of excitation signals in different frequencies and / or waveform shapes are introduced simultaneously to the imaging volume through one or more excitation coils, and the response spectrum is measured also in real-time and / or after excitation. Systems of the invention can be compact and portable, with small magnets providing the deterministic inhomogeneous magnetic field. Preferred embodiments include integrated circuit transmitters and receivers. Preferred systems of the invention are suitable, for example, for point of care medical diagnostics.

Description

CLAIM FOR PRIORITY AND REFERENCE TO RELATED APPLICATION

[0001] This application claims priority under 35 U.S.C. §119 to prior provisional application 60 / 706,406 filed Aug. 8, 2005.FIELD OF THE INVENTION

[0002] A field of the invention is the field of magnetic resonance. Example applications of the invention include, but are not limited to, microscopic resonance imaging, spectrometry, and general resonance imaging. BACKGROUND

[0003] Magnetic Resonance Imaging (MRI) is an imaging technique used primarily in medical settings to produce images of the inside of biologically-relevant objects such as the human body. MRI is based on the principles of nuclear magnetic resonance (NMR); a spectroscopic technique used to obtain chemical and physical information about molecules and chemical bonds. In a typical MRI imaging device, a large direct current magnetic field is applied and a perpendicular alternating current magnetic field is applied for excitation. The alternating current creates a fie...
